Patent DE-2611038-A1 (DE)
Inventor: KAISER HILDEGUND ING GRAD
IPC: H04Q1/32
Filed: 1976-03-16
Abstract: In a time division multiplex system for PCM signals, the switching codes which control switching in the exchange equipment of a telephony network must be transmitted, as well as telephony signals. If two-wire connections between exchanges are used, the codes are transmitted via the speech cores (a, b) in both directions. To reduce power consumption, it is necessary to replace the relays which have been used in the code converters until now by fully electronic devices. For this reason, several transmitter-sensor combinations (Q1, F1, ... Q4, F4) are combined into one code converter, each transmitter-sensor combination being provided for one high or low impedance evaluation potential. <IMAGE>

Title: Control circuit for electronic indicator - with protection against mains supply failure uses battery and switches off display if mains fails
Inventor: SEIBT ARTUR DR ING
IPC: H02J9/06
Filed: 1976-04-30
Abstract: The indicating circuit typically has a LED display and a ring counter for displaying different quantities in succession. The circuit is composed of integrated MOS elements and diode-resistor type logic, and also employes opto-electronic couplers in the input circuits. A battery provides the emergency supply. Failure of mains power is followed by switch off of the LED display and blocking of the photocouplers. The battery maintains the stored information circuits. The battery (T3) is recharged by the mains, but should its potential fall too low during a mains outage all the stored information is cancelled and the indicators locked out. If the battery remains sufficiently charged then on return of mains power the whole circuit picks up again and continues to function normally.

Title: Liq. circulation for axial balance of centrifugal pump - leaves static pocket round shaft seal to prevent erosion
Inventor: HANAGARTH WOLFGANG DIPL ING
IPC: F04D29/22
Filed: 1977-03-12
Abstract: The impeller (4) of a centrifugal pump has a flange (8) on its back a short distance above distance above the inlet to the blades (5). The casing has a projecting flange (11) which leaves a throttling gap (1) between itself and the flange on the impeller.
